I want to use Notepad++ to find/replace large chunks of code, but a hefty part of it deals with arrays. How can I put a "variable" in Notepad++'s Find/Replace window so that part of it can be saved and not overwritten?

The below example isn't perfect, as it could be converted using two simple find/replace searches, but I'd like to do something to the effect of Find: o[*] and Replace: p*.
